New Method of Friction Assemblies Reliability and Endurance Improvement

Abstract:

Thus a new method of shaft necks processing is suggested for practical application, including application of soft antifriction metal coating, chosen from group: indium, tin, copper, silver, which differs that the coating is applied by electroerosion alloying on the shaft neck surface with discharge energy 0,01-0,03 J in the final operation, or the coating of copper or silver is applied with discharge energy 0,04-0,4 J and subject to post-processing, for example nonabrasive ultrasonic finishing. In such cases the surface layer with the microhardness less that the microhardness of the backing is formed. That promotes the fall of friction assembly normal operation and reduces the possibility of babbit microfractures formation in cubic crystals SnSb, which subsequently become the center of fractions formation in bulk of the layer.
